Radiation Hardened Negative Low
Dropout Adjustable Voltage Regulator
The radiation hardened ISL72991RH is a low dropout
adjustable negative regulator with an output voltage range of
-2.25V to -26V. The device features a 1A output current
capability, an adjustable current limit pin (I
shutdown pin (SD) for easy on/off control.
The device incorporates unique circuitry that enables
precision performance over the -55°C to +125°C temperature
range and post-irradiation. Specifications include a reference
voltage of -1.25V +40mV/-50mV (max), line regulation of
±25mV (max), and load regulation of ±15mV (max).
Constructed with the Intersil dielectrically isolated Rad Hard
Silicon Gate (RSG) BiCMOS process, these devices are
immune to Single Event Latch-up and have been specifically
designed to provide highly reliable performance in harsh
radiation environments.
Specifications for Rad Hard QML devices are controlled
by the Defense Supply Center in Columbus (DSCC). The
SMD numbers listed here must be used when ordering.
Detailed Electrical Specifications for these devices are
contained in SMD 5962-02503. A ‘hotlink’ is provided on
the Intersil website for downloading.
